RHEL/CentOS 7 uses SystemD predictable network interface names. This post shows you how to rename a network interfcae to eth0,/em>without modifying the kernel commnad line or any udev rules, and without requiring a sytem reboot. This blog post describes the fastest way that I know to change the root password on a RHEL7 platform if you do not know or have forgotten the root password. A typical use case is the RHCSA 7 exam. This blog post discusses my viewpoint that systemd adds no value when used on an enterprise server such as RHEL7 and, in fact, results in a misuse of scarce corporate or governmental resources for no discernable increase in security or productivity. Want to test your RHCSA test preparedness? This blog post provides details of a custom CentOS 7.2 VM which enables you to do exactly that. As close to the real exam experience as possible. |
